Today we talk about hypothetical types of biochemistry, exploring how life might build itself in alien environments where carbon and water are nowhere to be found.

Every organism on Earth relies on carbon as its structural backbone and liquid water as its universal solvent. But astrobiologists and bio-chemists actively model theoretical organisms built on radically different chemistry - life that could thrive in liquid methane seas, scorching high-pressure worlds, or freezing interstellar clouds. In this episode, we are diving into alternative elemental backbones like silicon, boron, and arsenic, and swapping out water for solvents like liquid ammonia, methane, or supercritical carbon dioxide.

We're dissecting the chemical hurdles these exotic metabolic engines would face: why silicon chains tend to lock up or explode around oxygen, h ...
